Hi Assaf! Thank you for your quick response!
There is always multiple ways to do things. The git tool has a diff tool built in that makes file comparison easy. I have run across multiple times that copying one tree over another is desirable. In another bug message thread, we found that the cause was cp alias to 'cp -i' for root user was the actual cause. This still left the incorrect operation of the interactive operation when both -i and -f is used. I think that in some cases the need of override the '-i' with '-f' maybe very desirable. So maybe having the '-f' cancel or override the '-i' operation might be a good change. Thanks!
